My research uncovered an old society of some sort - very secretive - who do a ritual here, every ten years or so, to appease Malacath, or honor him. I could not get much information on them, but I have seen marks of their rites here. These curious door locks are part of it, for they are not part of the original city, near as I can tell. We know they holed up in the old city. How did they eat? I hope more is revealed once we get in. And there is, I believe an old symbol for Clan Farhun. That must be wrong though, i don't think they were one of the clans in Old Orsinium thousands of years ago.
